soc/tegra: cbb: Clear ERR_FORCE register with ERR_STATUS

Browse Source 
When error is injected with the ERR_FORCE register, then this register
is not auto cleared on clearing the ERR_STATUS register. This causes
repeated interrupts on error injection. To fix, set the ERR_FORCE to
zero along with clearing the ERR_STATUS register after handling error.
